citizens of the' United;` States; residin atl Hempstead, in the countyoffNassau, ,tate

of New Yorki, havein'vented certain: new-and usefuliflmprovementsCar-'Heating Systems, of whiclrthe following; isa Aspecifications:reference ybeing .had to the: drawing ao-l com and forming- -part of "ithe: same.

y' invention relatesto cheating 'railway cars, :more particularly'thoseJ` propelled fby steam, u eiqzrlpsive,v or' 'other' t the exhaustoff-Which is. highly heated, and the-object@ off the inventioni is to'provide e meansiorf utilizing. the! heat@ 'ofthe exhaust to heat the canor'cars'.l

A further objectofthe invention 1s to roi vide devices `for thispurpose-whichsha be in; the yforward cham simpler'in; construction `andefficient in opera? tion. Incarryin :out my invention in. its referred:form arrange below the car'` and at each'endithereof--a casing or'chamber and provide=the same withpipes or conduits open toI the air fattheir vouter ends, and at their in nercends communication 4with aconduit extending throughout the length' of the car and located `insidethe same. q onduit is provided atfsuitable points-With eopenings for theescape -of air, so that the the o en ends-oiy the pipes iger as the carstravel will be delivered to the interior conduit and from that deliveredto the-interior of the car.

air v received by VFor the purpose ofheating the air thusre- `ceivedandjdelivered," I provide means -for discharging the exhaust fromthe-engine into the forward casing, or-b'oth, so that the airreceivingpi es thereinl will be continually bathed in. t e highly heated gasesconstituting the exhaust.y The result is that the air in passing throughthe heating pipes abstracts-heat therefrom and thus heated issues intothe interior ofthe car. Such an embodiment of the inventionisillustrated inthe accompanying drawing, in which Figure 1 is adiagrammaticsection view taken longitudinally through the center of 'acar to whichfmy invention `,is applied, and Fig. 2 is` an under'planview of the same.

The floor or bottomof the car, which may of course be of any type, isindicated by .1. At the ends thereof' and belowv the -floor are chambers2, 3, having outer walls 4', 5 inner Walls, 7, and intermediatepartitions 8, 9,

heated gases from the engine, anjd beingthiis' heated give up their heatto the air assing through them, and it will therefore e seen? thatheated air is delivered to the interior V'of the'car-from the conduits13, 14. F'rom the chambers the exhaust is discharged into the atmospherethrou h openings 19, 20.

One of the chie? advantages in my'inven'- tion, besides the matter ofeconomy, lis that` of ventilation. It will be seen that' the heated airis drawn from the outside arid" suppliedin large volume to ti'einsideofthe car and distributed along the rows ofseats, where most needed. Bymeans of dempers` 21, 2 2, in the inner walls of the chambers 2,

3 the heating and ventilation of the car may 100 duits 13, 14. ln WarmWeat er the forward 105 damper Vmay be placed Wide' open, thus cuttingoii the vsupplyof air, while the rear' Idamper is closed, thifiect beingto draw air from underneath the seats and :dischar e it outside throughthe rear chamber. n 110 15 the heating apparatus eliective.'

'60 wan o this-case if the ventilators vin the top of thev car are open,fresh air will enter therethrough,

engine.

It will also be clear that only one chamber and accessory parts maybeused if desired but in su'ch case the car must be turned around for itsreturn travel, in order to make I prefer, u'ip both ends of the caralike, at either end may be `the forward end, as ordinary street carsare usual-ly however, toe as shown, so t I handled.

Having now described the preferred embodiment of my invention, what Iclaim is.: 1. In a car-heating system, the combination of a chamberhavirw air-receiving pipes, a compartment into which said charge, meansfor h'eating the air'm its passage through said'pipes, means fordelivering the air from thj.I said compartment into the interior of thecar, and means for permitting more or less of the air to escape from thecomartment into the atmosphere, thereby reguating the uantity of airdischarged into the car, as set orth. v 2. Ina car-heating system,` the'combination of a chamber having air-receiving pipes, through the saidpipes, -a compartment receiving air from the said pipes and havinv anescapeA aperture for the escape of heate air from the coni artment intothe atmosphere,

40 means for de ivering air from the compartment to the interior of thecar, and a damper controlling said escape aperture, 'whereby more orless-of the air in the compartment may be permitted to escape into theatmos- 4,5 phere, as set forth.

3. In Aal car-heating system, the combination of a chamber havingair-receiving pi es extending rearwardly and open at their orf Ward endsto the atmosph re, means for heatingthe said pipes-where y the airpassing throu vh the same will be heated, a compartmentI ocated t o therear ofthe chamber and receiving the air from the said pipes, the rearwall of said compartment having an a erture `for the escape of air intothe atmosp ere, a'

conduit for delivering air fromy the com artment into the interior ofthe car, and a amper for regulating the escape of air into theatmosphere through the aperture in the rear the compartment, wherebymore or less air will escape instead of being 'delivered into the car,as set forth.

4. In a car-heating system, the combina- -tion of a chamber havinair-receiving pipes,

a compartment into W pipes dismeans for heating the air inv its passage'ich said pipes discharge, having an aperture for the escape of heatedair from the compartment into "the atmosphere, means for heating the airin. its passage through the said pipes, a conduit for delivering airfrom the compartment into the 70 interior of -the car, a damper for the.said e'scape aperture, and means for o erating said' damper, wherebymore or less o the air may be permitted to escape into the atmosphere,as set forth. 75

5. In al car-heatin system, the combination of a pair of cham ers', oneat each end og I. the car, air-receiving pipes extending throug j. thechambers and open toward the adjacent end of the car, whereby one or theother set so of pipes will receive air, according-to the d1- rection ofthe car's travel, means for heating lthe' air in itspassage through thepipes, compartments receiving air'from the. respective lpipes, saidcompartments being in commuf nicatio'nv with the interior of the car andbeing provided also ywith openings into the atmosphere, and dampers yfor said openings, whereby the quantity of air delivered to the car may"be regulated by permitting more or less of the air 1n the compartmentto escape into the atmosphere, as set' forth.

6; Ina car-heatin system, the combination of a 4air of chambers, onelocated at each end of t e car, pipes in the chambers-open toward theIadjacent ends of the car, com

partments behind the dpipes to receive air therefrom and provide withopenings1 into the atmos here, conduits arranged to neceive air from t ecompartments and deliver -the sar'ie to the interior of the car,connections' from the propelling motor of the car whereby the exhaust ofthe motor isdeliveredlto lthe .chambers to heat the airreceiving.pipestherein, and dampers for the said openingsin .the compartments, wherebymore or. less of the air in the com artment receiving air from the pipesmay e permitted to esca ev into the'atmos hereand the remainder edelivered into `t e car, as set forth.

7. In a car-heating system, -the combination of a transverse chamber atone end of the car, provided with air-receiving pipes open toward theadjacent end of the car and eX- tending rearwardly through the'ch'amber,a 115 compartment at the rear of the chamber, rc-

es and having in its rear w'all an aperture for t e escape of heated airinto the atmosphere, a similar but oppositely arranged chamber andcompartment at V the other 'end of the car, la motor for repelling thecar, means for delivering t e eX-' haust` of the motor to the saidchambers, whereby air Howing through the air-receiving pipes will beheated, conduits at the sides of thecarconnecting the com artments androvided with apertures for t e discharge o air into the car, and dampersfor the escape apertures in the compartments, as set forth.
